SLIDING AND SWINGING SASI-I.

Speccaton of Letters Patent.

Patented Oct. 3i, 1916.

Application led August 12, 1915. Serial No. 45,107.

To all whom t may concern:

Be it known that I, PETER J. McAvnY, a citizen of the United States, anda resident of the city` of Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in Slidingand SwingingSashes; and l do hereby declare that the following is afull, clear, and exact description of the same, reference being hadtotheaccompanying drawings, and to the numerals of reference marked thereon,which form a part of this specification.

This invention relates to an improved type of window constructionwherein sliding sashes are mounted in a frame and each of said sashes isprovided with an auxiliary glass sash which is pivotally mounted,whereby the glass sash may be rotated in the main sash into an open positionor reversed there in if so desired to facilitate cleaning thereof.

It is an Object therefore of this invention to construct animproved typeof window wherein sliding sashes are provided operating in the usual andordinary manner for adjustment, said sashes being equipped withauxiliary glass sashes pivotally mounted and adapted to be adjustedtherein to reverse the pane of glass in the sliding sash to clean oropen the same.

It is also an object of this 'invention to provide a window constructionwherein main sliding sashes are mounted in a window frame, each of saidsashes being provided With an auxiliary glass sash pivotally mountedtherein for adjustment, and with means operated by a suitable key tolock said glass sashes in the main sliding sashes.

It is also an object of this invention to provide a window constructionwherein sliding sashes are mounted in a window frame, and mounted ineach of said sashes are auxiliary glass sasheshaving pivotal connectionwith said sliding sashes adapted to be locked tightly and sealed thereinor released for adjustment and reversal by means of suitable key'operated mechanisms inclosed within` the rails of the sliding sash andconcealed from view.

It is furthermore an important object of this invention to construct animproved type of window wherein rotatable glass sashes are mountedwithin the usual sliding sashes of the window frame to ypermit completereversal of the glass sash within the sliding sash, and with camcontrolled key of Fig. l, showing the lower sash of the '1 window. Figis a section taken on line 3-3 of Fig. l, with parts in elevation. Fig.et is a fragmentary sectional view taken on line 4.-4 of Fig. 2. Fig. 5is a detail section taken on line 5--5 of Fig. et. Fig.V 6

is a detail section taken on line 6-6 of Fig. 5. Fig. 7 is a fragmentarytop plan view of the lower' rail of the lower sash, with the glass sashomitted. Fig. 8 is a detail section taken on line 8&8 of Fig. t. Fig. 9is a detail section taken on line 9 9 of Fig. 4f.

As shown in the drawings, the window frame is denoted as a whole by thereference numeral l, of which the sill thereof is designated by thereference numeral 2, and mounted inv said window frame is a main uppersash` 3, and a main lower sash 4, which are substantially identical inconstruction.

plementary glass sashes, that in the upper sash being denotedby thereference numeral 5, and carrying a pane of glass 6, and that inthelower sash 4, designated by the reference .numeral 7, and carrying apane of Mounted in each of said main .l sliding sashes 3 and 4;,areauxiliary or sup-yy glass 8. 1 Said respective main and auxiliary fsashes may be constructed of any suitable material., either wood ormetal, as desired, and inasmuch as the construction and operation ofeach of the auxiliary glass carrying sashes is identical withreferenceto its sliding sash, a description of one will suflice. For this purposethe upper and lower rails of each of said sashes 3 and 4, are recessedor cored out, as clearly shown in Fig. 2,

and in each sash mounted in the recessed in therecessed portion of thelower rail of y'.-

each sash is a horizontal trough shaped member l0, which, however, isslidable vertically in said rail. The upper rail of the auxiliary sash7, isk cored out at its middle, as indicated by the reference numeral11, and inserted therein is a central pivot bolt 12, which is threadedtightly into Said trough member 9. A plate 13, is secured over the coredout portion of said auxiliary sash 7, and, as clearly shown in Fig. y2,the sash 7 has a sliding movement away from the trough member 9, limitedin its downward movement therefrom by the head of said bolt 12.Similarly secured in the lower slidable trough member 10, is a centrallymountedk pivot ybolt 14, which engages loosely into a cored out recess15, in the lower rail of the auxiliarysash member 7, said cored outportion being covered by a plate 16, provided for the purpose.

The loose pivotal connection thus pro* vided for the auxiliary sash 7,on said upper and lower bolts 12 and 14, respectively, permits the sashto be completely reversed into the main sliding sash 4, to fit snuglytherein, the looseness of said pivot bolts permitting any inaccuraciesof construction in this respect to be compensated for.

The manner in which the auxiliary `adjustable sashes are constructed andmounted in the main sashes is of particular Vnote. Reference to Fig. Gwill disclose thatthe end surfaces of the stiles of the auxiliary Sashesare slightly curved, as indicated by the reference numeral 17, and theinner end surfaces of the main sash are correspondingly curved on aradius equal to the dis tance to the central pivot bolts 12 and 14, sothat a snug fit of the auxiliary sash into the main sash when in normal.or reversed position is assured.

Another feature of construction to which I desire to call attention isthat in both the upper and lower sashes 8 and 4, the slightly curvedinner surfaces of the stile members against which the auxiliary sashes 5and 7, t, are convergent a very small amount toward the upper end, andthe stile mem-y bers of the respective auxiliary sashes 5 and 7, aresimilarly constructed in conver gent relation. The amount ofconvergence, however, is very small, and is shown inv F ig. 1 of thedrawings somewhat exaggerated, but suliicient so that when said aux`iliary sashes 5 and 7, are moved upwardly the small amount required totit the same tightly within the sliding sashes 3 and 4, they arewedgingly engaged therewith.

llfhen the lower trough member l0, is thrust upwardly, the auxiliarysash 7, seating therein, is thrust upwardly tightly within the uppertrough member 9, so that said auxiliary sash is thus held securely inthe main sliding sash Then the lower trough member 10, is released andmoved downwardly, the auxiliary sash 7, moves downwardly until limitedby the head of the upper pintle bolt 12, the sash of course moving clearof the trough member 9, and similarly at the lower rail of saidauxiliary sash 7, the trough member 10, moves downwardly and away, sothat the auxiliary sash can then be swung and reversed in the main sashif so desired.

Mechanisms for operating the lower trough member 10, to effect theseoperations, consist of a central actuating bar 18, having a centralcut-away slot or aperture 18, therein, which fits over a short rotatablearm or cam 20, rigidly secured upon a bolt 21, which is mountedtransversely in the lower rail of the sash 4, and has a squared head 22,to receive fitted thereover a key for -rotating the same and said camtherewith. At each of its ends, said bar 18, is linked to auxiliaryactuating bars '19, and connected at the pivot connection between saidbar 18, and bars 19, and also at the extreme outer ends of said bars 19,are cams 23, pivoted uponv fixed pintles 24, secured transverselythrough the cored out portion of the lower rail of the sash 4. Each ofsaid cams 23, consists of two parts similar in construction, as clearly.shown in Fig. 5, and each part is provided with a curved slot 25, en-

gaged within whichis a pin 26, having integral therewith an extension27, which projects upwardly from between the two parts of the camthrough an aperture provided in the trough member 10r and has insertedthrough its upper end a split retaining pin 28. The stilesfof each ofsaid 4sashes 8 and 4, as clearly shown in Figs. 4 and 8, are providedwith tongues 29, for engagement with the end of the lower trough member10, which is slotted for the purpose, to assist in guiding the same inits movement.

rPhe operation is as follows: If it is desired to reverse the pane ofglass in either one of the sliding sa'shes 3 or 4, as the case may be,when the 'sashes are in the closed position illustrated in Fig. 1, 'asuitable key is inserted over the squared end 22, of the bolt in thebottom rail of the sash and. turned in a co'unterclockwise direction,thus throwing the cam 20, shownin Fig. 4 to the left end sliding the bar18, therewith. This sliding movement of they bar 18, imparts Yacorresponding movement, ofcourse, to thebars 19, and consequently causesa clockwise rotation of the four :cams 23, which hold the trough member10, thrust upwardly, thus drawing the same downwardly, due to theengagement in said cams* of the pins 26, and 'this allows the auxiliarysash 5 or 7, as the case may be, to drop downwardly a small amountsuflicient at least to disengage the same from the upper trough member`9, shown in Fig. 2. The downward movement of the `auxiliary sash islimited by the head of the bolt 12, engaged therewith, fand of course,due to the il ment by the heads of said pintles: Said aux'.

fact that the trough member 10, drops downwardly to a greater distancethan the auxiliary sash member so as to be out of engagement therewith,the auxiliary sash member and pane of glass mounted therein may then berotated about the centrally disposed pivot bolts 12 and 14, and 4ifdesired completely reversed in the sliding sash.

Similarly when said key tits over the squared end 22, of the actuatinghead or bolt is turned in a clockwise direction, the slide bar 18, andbars 19, are moved to the right, thus drawing the cams 23, into aposition to elevate the lower trough member l0, which in turn elevatesthe auxiliary sash which is thus thrust upwardly against the uppertrough member 9, in sealing locked relation therewith so as to be rigidin the sliding sash.

I am aware that various details of construction may be varied through awide range without departing from the principles of this invention, andI therefore do not purpose limiting the patent granted otherwise thannecessitated by the prior art.

I claim as my invention:

l. In a window construction of the class described, a main sash, aglass-carrying auxiliary sash mounted in said main sash, pintle boltsmounted centrally at opposite sides of said main sash and havingprojectd ing headed ends, said auxiliary sash being engaged by saidheaded ends and shiftable thereon and limited in said shiftingmoveiliary sash being pivoted to rotate upon said pintles, and means forshifting said auxiliary sash on said pintles wedgingly to look the samein its closed position.

2. In a window construction of the class described, a main sash, aglass-carrying aux lllary sash mounted in said main sash, p1n
